The ball python is a medium-sized, robust, non-venomous snake belonging to the Pythonidae family. Its body is cylindrical, solid, and covered with smooth, shiny scales. Its natural coloration is dark brown with lighter markings, although more than 6.000 morphological varieties ("morphs") have been developed in captivity through selective breeding. Its head is relatively small and is equipped with thermoceptive pits in the labial region, which allow it to detect the heat emitted by its prey, even in the dark. It has a flexible jaw and recurved teeth, specialized for holding prey while strangling it by constriction. Its metabolism is slow, allowing it to go weeks without feeding. It has functioning lungs and a terminal cloaca, and lacks an external ear, perceiving vibrations from the ground. It inhabits warm areas of savanna and open forest, where it uses abandoned burrows and underground shelters for thermoregulation and to hide from predators.

The ball python is primarily crepuscular and nocturnal. During the day, it remains hidden in burrows, hollow logs, or under leaf litter, emerging at dusk to hunt. It is a solitary species that only gathers to breed. It has a unique defensive behavior: when threatened, it curls into a ball, hiding its head in the center of its body; hence its common name "ball python." It is calm and non-aggressive, making it one of the most manageable snakes in captivity. It can remain motionless for days or weeks if environmental conditions are unfavorable. During molting, it becomes more irritable and its vision is reduced due to its veil. It moves slowly, and it uses its forked tongue to capture chemical particles from the environment, interpreted by the Jacobson's organ. Its reproductive behavior includes rubbing and vibrating to court the female.

Classified as Near Threatened by the IUCN, the ball python is facing a progressive population decline in several areas of West Africa. Although still common in many regions, its high demand in the international pet trade has led to the massive extraction of wild specimens, particularly adult females. Although authorized breeding farms ("rancheo") exist, studies indicate that the current level of exploitation is not sustainable in the long term. Furthermore, its habitat is threatened by agricultural expansion, fires, and urbanization. It has been listed on CITES Appendix II since 1977, which regulates its export. In Europe and America, thousands of specimens live in captivity, where intensive breeding has generated a highly profitable commercial industry. Some programs seek to promote responsible trade and in situ conservation through agreements with local communities that protect key habitats and improve management practices.
